  SYNTHESIS AND ANTI-HIV ACTIVITY OF THYMIDINE ANALOGUES BEARING A 4?-CYANOVINYL GROUP AND SOME DERIVATIVES THEREOF

  摘要：

  Treatment of 3'-O-tert-butyldimethylsilyl-2,5'-dideoxy-5'-oxothymidine (4) with potassium or magnesium nitromethanide afforded in good yield the resolvable epimeric mixture of the expected blocked nitronucleosides 5 which upon dehydration led to the corresponding E-nitroenofuranosylthymidine 6. Nucleophilic attack of cyanide onto the nitrovinyl group led to a nucleoside analogue bearing a terminal 1-cyanovinyl group (7), a soft electrophilic group which, upon reaction with benzeneselenol, underwent a conjugate addition to the phenylselenonucleoside derivative 9. All these compounds, eventually de-O-silylated, were subject of in vitro biological testing, some exhibiting interesting cytotoxic or antiviral properties.
